(CNN)The Pentagon could in the coming months lift the ban on transgender people openly serving in the U.S. military, after Defense Secretary Ash Carter announced Monday a plan to study “readiness implications of welcoming transgender persons to serve openly.”

Carter made the announcement in a memo outlining a pair of directives to both study the effect of transgender service men and women over the next sixth months, as well as adding the new protocol that any personnel diagnosed with gender dysphoria or who identify as transgender will have their paperwork for dismissal from the military reviewed at the highest personnel levels in DOD.

“At a time when our troops have learned from experience that the most important qualification for service members should be whether they’re able and willing to do their job, our officers and enlisted personnel are faced with certain rules that tell them the opposite,” Carter wrote in his statement. “Moreover, we have transgender soldiers, sailors, airmen, and Marines – real, patriotic Americans – who I know are being hurt by an outdated, confusing, inconsistent approach that’s contrary to our value of service and individual merit.”
